ASR9001-LC stuck at Rommon - Why no disk?

[anudhs]

Could anyone please assiste me here?

I have a Cisco 9001-LC that is stuck at rommon.

I'm trying to turboboot using asr9k-mini-px.vm-6.4.

In Rommon, I am not seeing any Disk available and I am unable to see the usb when it's inserted.

dev
Devices in device table:
id name
bootflash: bootflash
configflash: configflash
rommon B6 >
rommon B6 > dir bootflash:
program load complete, entry point: 0x100000, size: 0x2ac20
File size mode File name

rommon B7 >
How can I get disk0: and the USB to show up?

When you issue : dev (you should see the USB as disk0 or disk1) - if not the USB not recognised

use lower USB stick like 4 or 8GB with Fat formatted to work.

or you can also use TFTP method :
